The impact of cloud computing on industry and end users would be difficult to overstate: many aspects of everyday life have been transformed by the omnipresence of software that runs on cloud networks.

By leveraging cloud computing, startups and businesses are able to optimize costs and increase their offerings without purchasing and managing all the hardware and software. Independent developers are empowered to launch globally-available apps and online services.

Researchers can share and analyze data at scales once reserved only for highly-funded projects. And internet users can quickly access software and storage to create, share, and store digital media in quantities that extend far beyond the computing capacity of their personal devices.

Types of Cloud Computing

Public Cloud

Public cloud services are best for development systems and web servers. Your cloud computing provider will give you a slice of their digital space that they must share with other tenants.

These types of clouds are cost-efficient since a pay-as-you-go model operates most. You pay for the number of hours you need to use the cloud and can exit whenever you complete your work. There are no obligations that require you to pay more than you need.

Private Cloud

Private clouds offer what their name suggests: privacy. You do not have to share your digital space with anyone else. Private cloud platforms are typically built in-house, and they belong to you and your business. They can also be configured in a  third-party data center and still provide an advanced level of privacy.

Larger organizations and clients who are concerned about security favor private clouds. The reason for this is primarily the fact that these clouds offer more defense than their public counterparts. Companies that need to protect sensitive information like customer data rely on private clouds.

Hybrid Clouds

Hybrid clouds are the best of both worlds. If you are using a hybrid cloud, you can control an internal database and use the public cloud when needed.

There might be times when you will need to move data and applications from the private cloud to the public cloud, such as scheduled maintenance, blackouts, and natural disasters. The ability to seamlessly migrate information is perfect for cloud-based disaster recovery and preventing data loss.

The flexibility of hybrid clouds is excellent for scaling as any overflow can regulate in the public cloud. Furthermore, you can keep all non-sensitive tasks in the public cloud while safeguarding the essential data in the private cloud.

Regardless of how large your company is or what industry it serves, there will always be a cloud solution that best fits your needs. Take the time to compare the advantages and disadvantages of each kind before deciding.

Examples of Cloud Computing Services

Cloud Storage and Hosting

Keeping essential documents in a central online storage location makes it easier for everyone to access them. Cloud storage is vital for businesses with employees whom all need to obtain the same information to do their work. It increases collaboration and efficiency among organizations.

Cloud storage is also handy for personal use as you can keep your necessary documents on a web server to access later. Just look at Google Docs or OneDrive. You no longer need to carry around a flash drive to edit your spreadsheets or read your files.

Cloud Backup
Backing up files in the cloud is by far the most efficient way to ensure their availability. Cloud backup solutions create multiple copies of files and store data in different locations. This way, you do not have to worry that your files will be lost in case one of your or your provider’s cloud server goes down.

E-mail
People send about 105 billion emails every single day. Millions of newsletters, greetings, and reminders make their way into people’s inboxes across the world. None of this would be possible without the cloud infrastructure.

Business Intelligence
The availability of cloud-based BI systems triggered some of the most revolutionary changes in businesses. Complex data analytics, processing, and reporting systems are now available via the Internet at low price points. A single license can be transferred to multiple users, requiring no lengthy installation or setup.

Conclusion
Cloud technologies offer a variety of opportunities to businesses, independent developers, researchers, educators, and students. By understanding the different services, models, benefits and risks offered by the cloud, users can make informed decisions about how to best take advantage of its offerings.
